First and foremost, stay in school! I managed to screw up my first semester and then joined the army because it sounded like the thing to do at the time. I'm not saying I didn't enjoy it but it was only one of several options I could have taken at the time. After I got out I went back to school with a vengance and now I graduate from OU next semester.
Trust me on this one, college is way easier to handle than the military is. It may seem tough now, loosing friends always is, but it really isn't worth dropping everything. It might do you some good to head back home for awhile and do a semester at community college. That way you are close to home and the cost is way less.
Either way, think long and hard about what you do and do not make any snap decisions. Feel free to PM me if you need anymore advice man, I have been in similar situations several times and managed to pull through.
